Siemens SX 45 Specifications, Tests and Review

The Siemens SX 45 has a height of 13.4 cm, a width of 8.7 cm and a thickness of 2.7 cm. The weight of the phone is 303 g.

LCD displays are currently taking a back seat. This is mainly due to higher power consumption. In addition, they have the disadvantage of lower colour contrast, which can be reflected e.g. in the resulting photos. On the other hand, phones with LCD displays are in general cheaper than those with OLED technology.

Display Resolution of Siemens SX 45 is 240 x 320 pixels. A higher display resolution is a prerequisite for a sharper image. The standard for mid-range phones today is a Full HD resolution of 1920 × 1080 px. Cheaper phones, which usually have a smaller diagonal, have an HD resolution of 1280 × 720 px. Smaller resolutions can only be found in older models. Best phones, on the other hand, have a 4K resolution of 3840 x 2160 px.

Siemens SX 45 is equipped with MIPS R4000. The processor frequency indicates how many instructions phone can process in 1 second. The higher the frequency, the better the performance. Standard processor frequency range today is between 1.8 GHz and 2.8 GHz. Siemens SX 45 reaches the frequency of 150 MHz.

An additional option to increase the storage capacity of this model is to insert a memory card.

RAM memory of the Siemens SX 45 is 32 MB. Most powerful phones currently have an operating memory of 12 GB or more, which is especially useful for demanding users such as gaming enthusiasts. Normally, phones nowadays have 6 to 8 GB of RAM, which means that the phone can easily handle normal operation and more demanding applications. Operating memory of less than 4 GB is found in lower-end phones or older models, and they are suitable for low-end users who don't use demanding applications and have the phone more for basic use.

The operating system in this case is Microsoft Windows CE 3.0.
